Causes of black and smelly rotten roots of hydroponic Fu Guizhu
First, hydroponic bamboo is not changed for a long time, and the water quality becomes turbid, resulting in lack of oxygen in the water.
Generally, when the rotten roots of Fu Guizhu in hydroponics are black and smelly, it is necessary to do a good job of root treatment and cut off all the damaged rotten roots. Plants should be disinfected and soaked in potassium permanganate solution.
Then, it is necessary to change the water. Note that in order to maintain water quality, water can be changed regularly. You can use dried tap water when changing water.
Second, Fu Guizhu's roots are diseased or infected by bacteria, which causes Fu Guizhu's rotten roots to be black and smelly.
You can cut off the infected part of Fu Guizhu, and be careful to cut it hard. Only when you are sick should you cut it off until the incision turns white.
After pruning, dry the wound and cultivate it again by hydroponics.
When pruning Fu Guizhu, we must pay attention to the fact that the pruning tools must be disinfected in advance and the plants must be cut off from all the problematic parts.
What should I do if the watered bamboo turns yellow?
1. Water quality problem: For hydroponics, water is the basis of Fu Guizhu's growth, and naturally it is also an important aspect that causes leaves to turn yellow. This time mainly depends on whether its root system is fresh. If it leads to root rot, it is necessary to cut off the rotten root system and use cold boiled water instead.
2, the light is too dark: if you don't get enough sunlight, you can't form chlorophyll, and the leaves will naturally turn yellow.
3, the light is too strong: Fu Guizhu is not suitable for strong light, which will cause the leaves to turn yellow. In view of the above two situations, we should first cut off the yellow leaves and the rotten roots, and then put them in an environment with suitable temperature and astigmatism to make them grow well again.
4. Too much fertilization: Too much fertilization can easily cause flowers to turn yellow, mainly because the top of new leaves is dry and brown, the leaves are generally thick and dull, the protrusions do not stretch, and the old leaves fall off in brown. Change the water again at this time.
5. Insufficient fertilizer: The main manifestation is that the tender leaves are pale, yellow or light green, not green. At this time, the old leaves generally don't see any big changes. At this time, just add the right amount of fertilizer.
6. Television is adjacent: just like soil culture, you just need to stay away from it and put it in a suitable place to grow well.
7. Improper modeling: Fu Guizhu is prone to overgrowth. Therefore, when changing pots and adding soil, we should pay attention to pruning old and residual fibrous roots and redundant stems and leaves to avoid excessive consumption of nutrients and play the role of supporting roots and protecting leaves. If you don't pay attention to shaping, it is easy to cause the leaves to turn yellow.
Matters needing attention in cultivation of Fu Guizhu
1. In spring, cut the cut stem into leafless nodes ranging from 5cm to 10cm, or cut off the tip of the base to make it dry easily. Branches with stem tips that grow in the shade indoors for a long time are inserted into clean coarse river sand, watered, covered with plastic bags and kept moist, and can take root in about 25 days. Or insert the cut branches into water and take root at 25℃ for about half a month.
2. It is better to buy Fu Guizhu in the north in spring, and it will enter the suitable growth period after buying it back. Heating facilities in winter can also be purchased before the new year. Potted plants should be strong, with dark green leaves, bright Phnom Penh stripes, no dry tips, no feet, plant height less than 30 cm, and 3 to 6 branches. For hydroponics with various shapes, plants with uniform stem thickness, beautiful shape and no rot at the base and root system should be selected. In particular, Fu Guizhu does not grow well in alkaline soil and dry climate, and his leaves grow thin and dull.
